The effects of the ground on propeller noise have been measured experimentally for the very first time by researchers in the Aeroacoustics research team at the University of Bristol. In findings, published in the Journal of Sound and Vibration, the team found clear differences in the noise characteristics of propellers when over ground, known as ‘Ground Effect’, compared to when operated normally. They noted an overall noise increase when measuring at angles above the ground, with hydrodynamic and acoustic interaction effects being a key factor to the overall noise trends. It is hoped this research, tested in the National Aeroacoustic Wind Tunnel ...

A new study examining the effects of planting a wildflower meadow in the historic grounds of King’s College, Cambridge has demonstrated its benefits to local biodiversity and climate change mitigation. The study, led by King’s Research Fellow Dr Cicely Marshall, found that establishing the meadow had made a considerable impact to the wildlife value of the land, while reducing the greenhouse gas emissions associated with its upkeep. Marshall and her colleagues, among them three King’s undergraduate students, conducted biodiversity surveys over three years to compare the species richness, abundance ...

CORVALLIS, Ore. – Researchers at Oregon State University and Baylor University have made a breakthrough toward reducing the energy consumption of the photonic chips used in data centers and supercomputers. The findings are important because a data center can consume up to 50 times more energy per square foot of floor space than a typical office building, according to the U.S. Department of Energy. A data center houses an organization’s information technology operations and equipment; it stores, processes and disseminates ...

The biology underpinning a rare genetic mutation that allows its carrier to live virtually pain-free, heal more rapidly and experience reduced anxiety and fear, has been uncovered by new research from UCL. The study, published in Brain, follows up the team’s discovery in 2019 of the FAAH-OUT gene and the rare mutations that cause Jo Cameron to feel virtually no pain and never feel anxious or afraid. The new research describes how the mutation in FAAH-OUT ‘turns down’ FAAH gene expression, as well as the knock-on effects on other molecular pathways linked to wound healing and mood. It is hoped the findings will ...

School accountability policies from around the world list an array of mandates and recommendations to improve schools. One prevalent mandate, especially in the United States, calls for the development of a school improvement plan (SIP). Since the 1970s, many U.S. states have required that schools develop SIPs, and, in the 1990s, the U.S. federal government started to require that all state-designated underperforming schools develop SIPs (IASA, 1994; Odden & Dougherty, 1982). These school accountability policy mandates assert that SIPs are an improvement tool for educators to use to set direction, ...

Hospital inpatients who develop an acute kidney injury (AKI) generally fare poorly after being discharged, and have few options for effective treatment.   A UW Medicine-led study published recently in American Journal of Kidney Diseases suggests that new tests might improve this narrative. In the study, “about 30% of the patients that came into the hospital developed AKI, which means in a matter of hours or days, their kidneys might be failing because of reaction to drugs or contracting sepsis,” said lead author Dr. Pavan Bhatraju, an assistant professor of pulmonary and critical care medicine at the University of Washington School of Medicine. Causes ...

East Hanover, NJ – May 23, 2023 – New data show that while individuals with visual disabilities were slow to recover employment because of the effects of the COVID-2019 lockdown, they have made headway, depending on their level of disability, almost meeting their pre-pandemic levels. Possible reasons for their slower recovery include major safety concerns due to the shortage of personal protective equipment, less access to vaccines, and their vulnerability to severe consequences of COVID, according to experts speaking during last Friday’s nTIDE Deeper Dive Lunch & Learn Webinar. Using data from the U.S. Bureau of Labor Statistics (BLS) for persons ages 16-64, the ...

About half of cigarette smokers and young adult non-smokers think that nicotine-based electronic cigarettes have the same amount or even more harmful chemicals than regular tobacco-based cigarettes, according to a Rutgers study.   The study, published in Addiction, measured perceived levels of harmful chemicals in e-cigarettes compared with cigarettes using national samples of more than 1,000 adults ages 18 and older who smoke cigarettes and 1,000-plus adults ages 18 to 29 who are nonsmokers. The study also measured associations with e-cigarette/cigarette relative harm perceptions, e-cigarette use and interest. About 20 percent of all participants ...

(Memphis, Tenn.—May 23, 2023) Scientists at St. Jude Children’s Research Hospital and the University of Texas Southwestern Medical Center studied the structure and function of a transporter involved in cancer and immunity. They captured six structures of the transporter, including when it was bound to an inhibitor, providing unprecedented insight into how it works. The findings, published in Cell, have implications for drug development.   Transporters escort substances across the cell membrane so that they can carry out their functions. Sphingosine-1-phosphate (S1P) is an important signaling molecule that regulates the immune system, blood vessel formation, auditory ...

If you look at enough dinosaur fossils, you'll see that their skulls sport an amazing variety of bony ornaments, ranging from the horns of Triceratops and the mohawk-like crests of hadrosaurs to the bumps and knobs covering the head of Tyrannosaurus rex. But paleontologists are increasingly finding evidence that dinosaurs had even more elaborate head ornaments not preserved with the fossil skulls — structures made of keratin, the stuff of fingernails, that were likely used as visual signals or semaphores to others of their kind. A newly described species of dome-headed dinosaur — a pachycephalosaur ...

UNIVERSITY PARK, Pa. — The tendency of cities to trap heat — a phenomenon called the “urban heat island,” often referred to as the UHI effect — can lead to dangerous temperatures in the summer months, but new Penn State research suggests that certain urban factors can reduce this effect. The study found that trees had a cooling effect on outdoor air temperature, mean radiant temperature and predicted mean vote index, a measurement designed to evaluate thermal comfort levels. Additionally, the researchers determined that higher building-height-to-street-width ratios — when taller ...

“This dataset presents the most comprehensive profiling of the aging adult mouse prostate immune profile to date.” BUFFALO, NY- May 23, 2023 – A new research paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 9, entitled, “Highly multiplexed immune profiling throughout adulthood reveals kinetics of lymphocyte infiltration in the aging mouse prostate.” Aging is a significant risk factor for disease in several tissues, including the prostate. Defining the kinetics ...

Organisations must enable mid-life women to thrive in the workplace by taking inspiration from societies such as China and Japan to encourage positive conversations around the impact of menopause, a new study reveals. But as they support older women in pursuing their ambitions and accessing career opportunities, organisations must ensure they do not hinder career progression through overlooked promotions, undervalued work, and lost opportunities. In Western countries, the menopause is traditionally viewed as a managed medical condition that creates physiological challenges which women must overcome if they are to function as effectively in the workplace ...

Session:  C98, Risky Business: Predicting Consequences of OSA Date and Time: 2:51 p.m. ET, Tuesday, May 23, 2023 Location:  Marriott Marquis Washington, Independence Ballroom, Salons E-H (Level M4)   ATS 2023, Washington, DC – Chronic obstructive pulmonary disease patients newly prescribed non-benzodiazepine benzodiazepine receptor agonists (NBZRAs) such as zolpidem (Ambien, Intermezzo and other brands), a class of hypnotic drugs prescribed for insomnia, did not have an increased risk of exacerbations requiring hospitalizations or of death than those prescribed ...

Powerful magnetic pulses applied to the scalp to stimulate the brain can bring fast relief to many severely depressed patients for whom standard treatments have failed. Yet it’s been a mystery exactly how transcranial magnetic stimulation, as the treatment is known, changes the brain to dissipate depression. Now, research led by Stanford Medicine scientists has found that the treatment works by reversing the direction of abnormal brain signals.  The findings also suggest that backward streams of neural activity between key areas of the brain could be used as a biomarker to help diagnose depression. “The leading ...

Carefully planned restoration of agricultural coffee landscapes can increase both farmers’ profit and forest cover over a 40-year period, according to a study publishing May 23rd in the open access journal PLOS Biology by Dr. Sofía López-Cubillos at the University of Queensland in Australia, and colleagues. Restoring patches of natural vegetation in agricultural land presents a trade-off for farmers: while the lost cropland can reduce profitability, increases in ecosystem services like pollination can improve crop yield. To investigate how conservation priorities can be balanced with economic needs, researchers developed a novel planning framework to model the ...

For the first time, researchers have shown that reduced oxygen intake, or “oxygen restriction”, is associated with longer lifespan in lab mice, highlighting its anti-aging potential. Robert Rogers of Massachusetts General Hospital in Boston, US, and colleagues present these findings in a study publishing May 23rd in the open access journal PLOS Biology. Research efforts to extend healthy lifespan have identified a number of chemical compounds and other interventions that show promising effects in mammalian lab animals— ...

Three studies now published in the open-access journal The Seismic Record offer an initial look at the February 6, 2023 earthquakes in south-central Türkiye and northwestern Syria, including how, where, and how fast the earthquakes ruptured and how they combined as a “devastating doublet” to produce damaging ground shaking. The two earthquakes, a magnitude 7.8 followed approximately nine hours later by a magnitude 7.6, took place at the tectonically active and complex junction between the Anatolian, Arabian, and ...

Rural Patients With Diabetes Experience Worse Health Outcomes Than Urban Patients Mayo Clinic researchers conducted a study within their health care system to identify factors associated with quality of care among rural and urban patients with diabetes. The study evaluated patient attainment of a five-component diabetic care metric, known as the D5 metric. This metric includes no tobacco use, hemoglobin A1C <8%, blood pressure <140/90, statin use, and aspirin use. Researchers considered age, sex, race, Adjusted Clinical Group score (a series of mutually exclusive, health status categories defined by morbidity, age, and sex), insurance type, primary care clinician type, ...
